(54) Concrete block system


(57) A dry-cast concrete block system (12) for use in a structure. The dry-cast concrete block system (12) comprises a support block (15) comprising a first coupling part (41) and a face block (13) comprising a second coupling part (29). The first coupling part and the second coupling part enable the face block to be coupled to the support block. The face block comprises a surface (141) adapted to be exposed when the face block is coupled to the support block and the dry-cast concrete block system is positioned in the structure. In one embodiment, at least a portion (16) of the surface has a cast texture with a natural stone appearance. In one embodiment, the structure is a wall and the concrete block system is a wall block system. For example, the wall may be a retaining wall and the wall block system may be a retaining wall block system. In another embodiment, the structure is a column and the concrete block system is a column block system. In yet another embodiment, the structure is steps and the concrete block system is a steps block system.
